@Davilla, I noticed with this file codec info on ATV4k says "DOVI" but with the screensaver rip that's DV it says "dvh1". Any significance to that?

Also, it doesn't seem to trigger the same as other HDR material. All other HDR material plays back as super contrasty mess since I don't have an HDR TV and apple removed the tonemapping feature. But, this plays back with more or less normal colors.

Yea, apparently the quality is a bit poor because of trying to keep the size down, and could be throwing colors off, but it's just to see if TV's actually get their DV tripped or not. Soo, it's good to go? Like if an entire UHD BD Rip was done with this method would it would be like playing a disc? Or must a different profile be chosen?
